Description

The invention relates to the construction industry and can be used in the construction of industrial and civil structures.

A known method of production by extrusion of plates intended for the construction and protection of structures from external influences, "BSE" "Soviet Encyclopedia", M., 1974, volume 8, p. 608. The disadvantage of this method is the high capital and operating costs.

The technical result is to reduce capital and operating costs due to the placement of the production of coating tiles in the areas of paper production and the use of its equipment.

This is achieved by the fact that the wet mixture of paper pulp with the addition of glue and gypsum is loaded into the extruder, the mixture is pressed through the extruder matrix with the formation of a profiled bar having a dovetail fastening and sealing edges at the outlet, and a profiled bar is produced on the plate conveyor , regulate the speed of the profiled beam, so that it is equal to the speed of the plate conveyor, periodically cut tiles from the profiled beam, move the last accumulator by transferring conveyors until they are completely filled, after which the device is turned off until the tiles are completely dried.

A device that implements the proposed method is an extruder with a continuously adjustable electric drive and a matrix for forming a profiled beam having a dovetail-type fastening and sealing lips; a plate conveyor, on which a string apparatus is installed, made with the ability to periodically engage with the plate conveyor, cut off the coated tiles from the profiled beam, unhook from it, and then repeat this cycle; accumulating conveyors installed with a height difference; rotary chutes made with the possibility of smoothly reloading the tiles from one accumulating conveyor to the next, in the direction of travel, accumulating conveyor.

The essence of the invention is illustrated by drawings, where:

- figure 1 is a General view of the device;

- figure 2 is a General view of the extruder;

- figure 3 is a cross section of a profiled beam.

The proposed method consists in the following nodes being manufactured:

- an extruder with a continuously adjustable speed of issuing a profiled beam and a matrix, which provides molding on the profiled beam of a protrusion for fastening such as dovetail and sealing edge;

- a plate conveyor with a string apparatus installed on it for cutting profiled timber into tiles;

- accumulating conveyors installed with a height difference;

- rotary estrus for smooth overloading of the tiles from one accumulating conveyor to the next, in the direction of travel, conveyor.

Prepare a wet mixture of paper pulp with the addition of glue and gypsum. Download the mixture to the extruder. It is pressed through the extruder matrix with the formation of a profiled beam having a dovetail protrusion and sealing lips at the outlet. Issue a profiled beam on a plate conveyor. Adjust the speed of the profiled beam, so that it is equal to the speed of the plate conveyor. The profiled beam is periodically cut into coating tiles. The latter are moved by accumulating conveyors until they are completely filled, after which the device for the final drying of the coating tiles is turned off. At the end of the drying process, the coating tiles include only accumulating conveyors, as a result of which all finished coating tiles on them are dispatched.

A device that implements the proposed method has an extruder 1 with a screw 2 and a continuously adjustable electric drive 3 connected to the screw 2 through a reducer 4. The screw 2 rotates in a thrust bearing 5. The extruder 1 has a loading device 6 for loading the mixture. At the exit of the extruder 1, a matrix 7 is installed, having a slot for forming a profiled beam 8, which has a dovetail fastening protrusion 9 and sealing lips 10. The extruder 1 is mounted above the plate conveyor 11, onto which the shaped beam is projected 8. On the frame of the plate conveyor 11, a string apparatus 12 is installed, adapted to interlock with the copiers 13 of the plate conveyor 11, cut off the cover tiles 14 from the profiled beam 8, detach from the plate conveyor 11, and then re-engage with a copier 13 of the conveyor 11. For smooth loading of the formwork tiles 14 from the plate conveyor 11 located above the accumulating conveyor 15, a rotary estrus 16 is used; from conveyor 15 to conveyor 17 - rotary estrus 18; from conveyor 17 to conveyor 19 - rotary estrus 20; from conveyor 19 to conveyor 21 - rotary estrus 22; from conveyor 21 to conveyor 23 - rotary estrus 24; from conveyor 23 to conveyor 25 - rotary estrus 26; from conveyor 25 to conveyor 27 - rotary estrus 28; from conveyor 27 to conveyor 29 - rotary estrus 30; from conveyor 29 to conveyor 31 - rotary estrus 32; from the conveyor 31 to the conveyor 33 - rotary estrus 34; from conveyor 33 to conveyor 35 - rotary estrus 36; from conveyor 35 to conveyor 37 - rotary estrus 38; from conveyor 37 to conveyor 39 - rotary estrus 40; from conveyor 39 to conveyor 41 - rotary estrus 42.

The operation of the device is as follows.

The electric drive 3 of the extruder 1 is turned on. The mixture is made and loaded into the boot device 5 of the extruder 1. A rotating screw 2 of the extruder 1 is extruded through the slot of the matrix 7 to form a shaped beam 8 having a dovetail protrusion 9 and edge seals 10. The electric drive 3 smoothly adjusts the speed of movement of the profiled beam 8, so that it becomes equal to the speed of movement of the plate conveyor 11. The profiled beam 8 without stretching or compression smoothly ozhitsya on the apron conveyor 11 and moves them. One of the copiers 13 of the plate conveyor 11 engages the string apparatus 12, which, moving together with the plate conveyor 11, cuts off the coated tiles from the profiled beam 8; 14 of a given length, and then uncoupled, after which it is engaged by the next copier 13, as a result of which the described operations are repeated throughout the operation of the device. Coating tiles 14 are moved by a plate conveyor 11 to a rotary chute 16, through which they are smoothly reloaded to a conveyor 15, from where they are reloaded to a rotary chute 18, and then to an accumulation conveyor 17 and so on until all accumulating conveyors 15, 17, 19, are completely filled. 21, 23, 25, 27, 29, 31, 33, 35, 37, 41. Then the device turns off until the final drying of the tiles.

After that, only the conveyors listed above are turned on, as a result of which all the coating tiles on it are issued for shipment.
